The Cato Institute’s Michael Tanner offers National Review Online readers an Obamacare progress report.

The law’s advocates … may have been left speechless by the news that Obamacare has tied an all-time low for public support, according to the latest Washington Post/ABC News poll. Just 39 percent of registered voters back the law, tying an all-time low last reached in April 2012. Fifty-four percent oppose it, and while that’s not a record, it represents a six-point increase in opposition over the past year.

Or maybe the law’s supporters simply have little response to the ongoing spate of news suggesting that, [economist and columnist Paul] Krugman notwithstanding, the law is still not working very well. For example, insurance companies have begun submitting their requests for rate increases for 2016, and those requests suggest that premiums could skyrocket next year. Already we’ve seen requests for increases for individual plans as high as 64.8 percent in Texas, 61 percent in Pennsylvania, 51.6 percent in New Mexico, 36.3 percent in Tennessee, 30.4 percent in Maryland, 25 percent in Oregon, and 19.9 percent in Washington. Those increases would come on top of premium increases last year that were 24.4 percent above what they would have been without Obamacare, according to a study from the National Bureau of Economic Research. At the same time, deductibles for the cheapest Obamacare plans now average about $5,180 for individuals and $10,500 for families.

In fairness, those rate-hike requests are just that — requests. State regulators are likely to trim them back, significantly in some cases. And other insurers in those states may be seeking smaller increases. We haven’t seen any data weighting increases by the number of people covered, so we should be careful about overstating the impact. In addition, many people are insulated from the true cost by the law’s subsidies, which is what makes the upcoming Court decision so important. Still, to recall P. J. O’Rourke’s famous dictum, if we thought health insurance was expensive before, look at it now that it is free.

New evidence also suggests that Obamacare is struggling to meet its goals for covering the uninsured. According to a report in Investor’s Business Daily, the Obama administration estimates that roughly 10.2 million people have enrolled in Obamacare plans and paid at least one month’s premium. This meets the White House’s revised sign-up goal announced late last year, though it falls below the Congressional Budget Office’s earlier projections. The CBO had originally projected some 12 million sign-ups through 2015, later lowering that estimate to 11 million. So, while we should recognize that Obamacare has significantly increased coverage, there clearly is a long way to go.
